But that was 20 years ago, and now IRL Cora, Alex Owens-Sarno (who was just 8 years old when they filmed Titanic), is all grown up and as adorable now as she was then.

Here's a side-by-side for funsies.

And Alex has nothing but fond memories of making Titanic.

She told BuzzFeed, "My mom has an amazing picture of me, Leo, Kate, and my little sister Rachel hanging out when they were resetting for the dancing scene. It's one of my favorites and is a reminder of just how lucky I am to have worked with two of the best actors out there."

"Leonardo DiCaprio was an absolute doll. He was so fun and charming. He loved to put a smile on everyone's face. [I'd often] be on his lap with a PB&J in between takes."

In fact, there's even a deleted scene where Jack sketches with Cora.

Alex explained, "James Cameron had done all of Jack's sketches [for the movie], and they had the sketch Jack does of Cora signed by Leonardo DiCaprio for me. Unfortunately, it got stolen out of someone's trailer. That would have been the most amazing keepsake!"

These days Alex dedicates herself to studying acting, and she recently earned her degree in writing from California State University, Long Beach.
